when I wear a silver bracelet in a pool where the water is treated with chlorine, the chlorine tarnishes the silver on the bracelet.
I want to buy the Apply 3 watch to use for triathlon training. This time of year my swimming is indoors in a pool with chlorine. If I am wearing the gray aluminum Apply watch will the finish on the gray aluminum be affected/damaged by the chlorine?

The only thing you have tho choose from is 38mm or 42mm. When you buy the band, it comes with three “parts”. The part that goes at the top of the watch and two parts for the bottom. One is for smaller wrists and the other is for larger ones. All you need to do is pick a color you like and order for the correct watch size. Don’t worry about wrist size! You’ll get what you need in the box and then choose what length you need!

The pin - tuck sports bands are very secure. I have used the original apple watch since it came out and have only used the sport band that came with it. I have hiked, biked, lifted weights, played with my children, rock climbed, danced....many activities...with out the watch ever coming loose or adjusting. It was very comfortable and the fit was great.
